Sulfur has the same amount, like all the other elements in group 16, has six valence electrons.
Answer:
Explanation:
Hello,
In this case, for the reaction between hydrochloric acid and sodium hydroxide, for 2.4 g of base, we can compute the neutralized grams of acid by applying the 1:1 molar ratio between them and their molar masses, 36.45 g/mol and 40 g/mol respectively as shown below by stoichiometry:
Best regards.
Answer:
Dilution is the process of decreasing the concentration of a solute in a solution, usually simply by mixing with more solvent like adding more water to the solution
Carbon source is the answer for ur question
Answer:
2.355atm
Explanation:
To get the pressure of helium, we need to get the mole fraction of helium.
The total mole fraction for any mixture of gases equals 1. Hence to get the mole fraction of the helium, we simply subtract the addition of the mole fractions of neon and argon from 1.
This means - 1 - 0.47 - 0.23 = 0.3
Now, to get the pressure of the helium gas, we simply multiply the total pressure by 0.3. This is 0.3 * 7.85 = 2.355 atm
